Diagnosis

Phymanthidae with base and column of variable appearance. Upper part of column with verrucae, which sometimes may be indistinct. A row of perforated marginal pseudospherules. Cinclides may be present at the base. No sphincter or a very weak, diffuse one. Marginal tentacles arranged hexa- or octamerously. Laterally the marginal tentacles are provided with weak or well developed protuberances in the form either of low knobs or of ramified branches. The discal tentacles sometimes resemble the marginal tentacles in part, more usually they are papilliform, sometimes very indistinct or even wholly absent. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal, sometimes with a slight tendency to be meso-ectodermal. Pairs of mesenteries arranged hexa- or octamerously [sic], many are perfect, the stronger with or without the directives, fertile. Retractors well developed, strong, diffuse or strongly restricted, reniform. Cnidom: spirocysts, basitrichs, microbasic p-mastigophores.
